An alternate base32 encoding as described by Douglas Crockford at: https://www.crockford.com/wrmg/base32.html

It is used for expressing integer numbers in a form that can be conveniently and accurately transmitted between humans and computer systems.

The encoding is designed to:

• Be human and machine readable
• Be compact
• Be error resistant
• Be pronounceable

A symbol set of 10 digits and 22 letters is used: 0123456789ABCDEFGHJKMNPQRSTVWXYL It does not include 4 of the 26 letters: I L O U.

A check symbol can be appended to a symbol string. 5 additional symbols *~$=U are used only for encoding or decoding the check symbol.

When decoding, upper and lower case letters are accepted, and i and l will be treated as 1 and o will be treated as 0. When encoding, only upper case letters are used.

The package can be installed as:

1. Add base32_crockford to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:base32_crockford, "~> 1.0.0"}]
end
```

2. Run mix deps.get in your console to fetch from Hex

iex> Base32Crockford.encode(1_000_000_000)
"XSNJG0"

iex> Base32Crockford.encode(1_000_000_000, partitions: 2)
"XSN-JG0"

iex> Base32Crockford.decode("XSNJG0")
{:ok, 1000000000}

iex> Base32Crockford.decode!("XSNJG0")
1000000000
